Pile splicing device for CFG piles

The utility model belongs to the field of CFG pile construction, and particularly relates to a pile splicing device for CFG piles. The problems that in the prior art, a pile repairing formwork is tedious to assemble, the pile repairing formwork can be displaced during vibration in the concrete pouring process, the center of a spliced pile does not coincide with the center of a CFG pile, an iron sheet winding drum is light in weight and prone to floating, and bottom concrete flows out are solved. The pile splicing device for the CFG piles comprises a left semicircular cylinder and a right semicircular cylinder which are symmetrically arranged above the CFG piles, the connected ends of the left semicircular cylinder and the right semicircular cylinder are hinged through a hinge mechanism, and the other ends of the left semicircular cylinder and the right semicircular cylinder are connected through a locking mechanism. The pile splicing device can be used in a turnover mode, is durable, easy to assemble, conveni
